I had a one subscription of XM web service and I have had Sirius for
about 2 months. I listen mostly to blues, swing and classical and XM
and Sirius are very similar to my ears.

As for every comparative review saying that XM wins hands down, I
haven't found that to be true. I have read every review I could find
comparing XM and Sirius before I made the commitment to buy one of
them. I have seen more reviews that favor Sirius content over XM. I
have included two such reviews below. The Edmunds review is the most
detailed review I have seen yet. They listen to both services for 60
days before giving their evaluation.
